Observational Evidence for Negative-Energy Dust in Late-Times Cosmology
Nikolaos E. Mavromatos, Vasiliki A. Mitsou
We perform fits of unconventional dark energy models to the available data from high-redshift supernovae, distant galaxies and baryon oscillations. The models are based either on b…
Confronting Dark Energy Models with Astrophysical Data: Non-Equilibrium vs. Conventional Cosmologies
J. R. Ellis, N. E. Mavromatos, V. A. Mitsou +1
We discuss fits of cosmological dark energy models to the available data on high-redshift supernovae. We consider a conventional model with Cold Dark Matter and a cosmological cons…
Quantum-Gravity Analysis of Gamma-Ray Bursts using Wavelets
J. Ellis, N. E. Mavromatos, D. V. Nanopoulos +1
In some models of quantum gravity, space-time is thought to have a foamy structure with non-trivial optical properties. We probe the possibility that photons propagating in vacuum…
